THE COMMONWEALTH & SOUTHERN CORPORATION OF MARYLAND, A CORPORATION OF MARYLAND BASKET TYPE ANCHOR Application filed March 1e, 1931. Serial No. 522,900. r

This. invention relates to a basket type anchor. It is concerned particularly with an anchor or footing structure advantageous for use ina subsurfacemanner for structural elements which .may be in the nature of towers.

More specifically, the V invention is concerned with the provision of an anchor useful for towers of high tension power lines, but it is to be appreciated that the invention may be used as an anchor or foundation member for any kind of structure other than these particular towers. I I j I One of the objects of the invention is'the provision of a structure fabricated of struc tural iron or steel wherein the parts are arranged and related so as to minimize the number of bends in the structure, thus facilitating not only the manufacturing end but also facilitating the 'asseinbly operation.

lso the arrangement is such that the forces are communicated from one element to another generally in straight lines so that no objectionable stress or'strain falls on bend formations. Other objects and advantages of the invention will appear in the following detailed description. l

Fig- 4 is an isometric view in illustration of the pyramid formation at the top ofthe anchor member with one, part cutaway and shown in section.

Fig. 5 is a somewhat diagrammatic view. illustrating the pyramid arrangement;

Fig. 6 is a view showing separately the several members from which the basket structure may be fabricated.

First, referring to Fig. 6, it willb'e'noted that there is an angle member 1, and an angle member 2. These twopieces may be utilized for forming'the base of the anchor; as shown in Fig. 3 the two members 1 may be reversed as'regards each other to form two sides of the base referenced 1 and 1a. Two other sides ofthe base are provided by two angle members 2, referencedQ and 2a. The pyra mid formation is provided by four le s or- 'MARYLAND', or BALTIMORE,

risers,-'one rising from each corner 0 the base. While there are four of suchrisers, only threedifferent structures needbe provided' as two maybe identical. One offthese legs is shown at 3, (Fig. 6). and in the bas ket structure two of these may be .used an} other is shown at 4, and av third at 5 Note These four legs. or risers come'together in that the members 3 and 5 are straightfand provided with no bends, and that the only so bend inthese riser members is in the mem pyramid formation as illustrated iniFig '4,

and then mounted thereon is what-may be termed a shoe 7,.angular in cross section and bent to provide an angular part 8. Due to the fact that the legs or risers are of pyramid formation complications arise in attaching them to the base members 1 and2. This has been accomplished without providing any bends or. angles in the metal other than the t. This has been effected by tippin some of the base members, as shown in. igs. 1 and 2.

l, and this may be accomplished by suitable bolts or rivets for which purpose member.

5 has holes 10, and the members 1 and 2 bend in the leg 5 andthe bend in theshoe i have holes 11 and 12. Thus the angled end of member 5 constitutes a connecting element for the'members 1a and 2a wherethey meet to form a corner of the base, as shown in Fig. 3. The member5' extends upwardly and angularly from its point of connection. 7

The memberfi is provided with bolt holes or rivet holes 13 and this member is bolted or riveted at thecorner formed by the base members 1 and 2 andit'extends upwardly and angularly from the base although the angle-is preferably not as great as that of member. 5. Member 4 also constitutes a con-' heating element between base members The two members?) connect to the other two corners ofthe base.

accommodatingffor thesejangles.

shown in Figs. 1 and 3,-one leg of one angle clip is secured to'member 2a; the extended.

leg part 16 of afmember 3 is connected to member las by means of bolts, rivets, or

the like taken through the member 1- and one'leg of theangle clip 17, and the exten I sion '16 as illustrated at 18, ,Figiy2. The.

C110. is of the samelconstruction and the above des V V legs of the upper part 7 of the member '5 may opposite corner where the anglercliprv is used soription of one will suffice for both.

These four legs or risers are in pyramid formation, and meet in an apeX at their upper ends, details of which willbe presently: V m V member 7' nts over the member 5; one leg of described. Accordingly, they allextend angularly inwardly and upwardly'fromthe base; This requires some arrangement for p This is accomplished bypositioning some or all of thebase members in an angular position sothat'whe're the base members are right angle in cross section, one legis at an angle to 'the 'vertical and one is at an angletothe horizontal; The-base member has shown iniFig. Bis disposedat any angle and its up;

"stead ofjdisposing the .member 2d at such 7 agreatfangle' Accordinglyythe basemember 212' .is not 'angled to. fit member/I3 ;1 similarly Q thef'base member lafis not angledrto fitthe other member 8; I l-loweverithe bolt'holes may advantageously be so located thatwhenthe membersila and 2a are bolted or riveted to the angle clip 17 they are given an angular} disposition similar to that of base members 7 1 and 2. The angle. at which the end 6 of member 5 is bent is sueh'as to correspond to I the angular portion ofba'se members 14 and 2a.- Inasmuch as angle clips 17 are used at the corners wherethe members 3 rise, one leg of the members3 mayadvantageously becut short as" at Accordingly, with all four base memberssimilarly angularly disposed and the bolt holes, etc.,iuniformly provided,

' to say, 2 and 2a'are identical and maybe used'ineither location and the same istrue' of 1 and 1a; Thus'thetwo membersi3'and the memb er'tf may have straight ends embody? ing no curves'or bends; the-only bend necessary being that of end 6' of member 5.

These four members :meet at their upper ends in pyramid formation Where they support the shoe 7 which may benof angle forma tion. The inanneriin whichithe members are pyramided andreceive the shoe, materially 7 facilitates assembly and provides a strong connection. *Asflshownin Fig; 3 the outside "corner'of member 5 1s 111 general allgnment with theijoutside corner of the shoe 7.

The legs of the member 4 may be beveled off at the upper end as at 27 and the member 4 may then be secured to both the members 3 by belts or the like passing through apertures 28 in member a and 29 in one of the legs of'ea'ch'member 3. Theshoe 7 serves to support a leg or strut 30 which may be of angle formation fitting inside the angle memb'er and bolted or riveted'thereto forwhich'" purpose member 7 shown in Fig; 6.

utilizing more'ior less 'standar'diangle struc-l tural'membera n that'only few different F types'of pieces,need beprovided; In fa'ct,--'

only two types of. members are used for the baseandthreefor the pyramid, Aside from this,-only the shoefand two angle clips need be, provided. Only two bend'operationsare necessary, one in the member 5, and one in the shoe. It will be noted that the bend line of the shoe is disposed immediately above the which is located in close proximity to'the base.

Angle members ordinarily have a little fillet on the inside of the bend as illustrated at 31, Fig. 5. In order to fit one angle member within another snugly, it is necessary to remove this fillet by chipping or the like, or grind off the outer edge of member 5. How ever with the present arrangement this is unnecessary by reason of the legs of the members 3 serving as fillers between angle members 5 and 7 thus to space the outside corner of member 5 from the fillet of member 7 The legs of the angle part 8 of the shoe are arranged so as to lie substantially flush with the members 3. This is afforded by the bend in the member 7 so that the legs of this member lie substantially flush against members 3 rather than member 5. When member 7 is bolted down there may be some spreading of the legs of member 7 below the bend line bringing them into substantially flush engagement with members 3.
